Drives for Vercel Sandbox in Private Beta
Vercel has introduced persistent, attachable storage for its Sandbox product, now available in private beta. Dubbed "Drives," these storage volumes have a lifecycle independent from any sandbox, meaning data persists even after a sandbox stops. Developers can create a drive once and mount it at a configurable path when starting a sandbox. When the sandbox stops, the drive remains available to attach to a later sandbox. To use Drives, developers need to install the beta SDK (`@vercel/sandbox@beta`) or CLI (`sandbox@beta`). During the private beta, a drive can be mounted read-write by only one sandbox at a time, and Vercel advises against using Drives for production data. Use cases include keeping agent workspaces across disposable sandboxes, retaining cloned repositories, dependencies, and build outputs, and managing data independently from the sandbox lifecycle. Interested users can sign up for the waitlist and learn more in the documentation.
Persistent storage for sandboxes enables stateful development workflows and agent workspaces across ephemeral environments.
